FLUSHING-PIPE FOR WATER-CLOSETS.

SPECIFICATION forming part of Letters Patent No. 376,137, dated January 10, 1888.

Application filed March 7, i887'A To aZZ whom, it may concern."

Be it known that I, THEoDoRE BUTLER, of the city, county, and State of New York, have invented an Improvement inFlushing-Pipes for Water-Closets, of' which the following` is a specification.

In flrst-class plumbing work the water-closet is very frequently not iucased with wood-work and the flushing-pipe is of polished brass andY extends from the water-closet up to the cistern. In this class of work difficulty is experienced in placing the closet in Yposition in relation to the wall and to the cistern with sufficient accuracy to make use of the rigid and non-adjustable couplings and bends heretofore en1- ployed for connecting the ends of the flushingpipe to the closet and cistern, respectively;

generally been fitted to place, and then special connections have been made for the respective ends of the brass pipe after the pipe has been bent while hot at the top and bottom ends, and this has necessitated delay in sending to the shop or manufactory and increased the eX- pense.

My presentimprovements are made with reference to adjusting the connections at the ends of the brass ilushing-pipe, so as to allow for the ordinary variations in the setting of theA closet and cistern.

I make use of a compound curved couplingpipe screwed upon the upper end of the vertical brass pipe and extending to the screwsocket upon the under side of the cistern, so that the upper end of Vthe straight brass pipe can be moved laterally to a slight extent to bring it vertical, and theV elbowA at the lower end of the'vertical brass pipeis provided with a socket and elastic packing and clamping ring to allow for adjustment and for makinga tight joint, and a screw-coupling between the closet and the elbow allows for adapting the pipe to the distance between the closet and the wall.

In the drawingsdigurc l shows the two ends of the flushing-pipe by vertical sections; and Fig. 2 is a perspective View of the closet, cistern, and flushing-pipe.

The rim A of the'water-closet is adapted to receive the plate B at the horn or tubular conserial No. 229,973; (No model.)

nection, and there is a screw-thread around the thimble B of this plate to receive the coupling-ring c, that clamps the hanged end of the nipple D to the ring e of leather or rubber. This nipple D is screw-threaded upon the outside, and is screwed into one end of the elbow F, and the socket of this elbow is sufficiently long to allow for the nipple D to be screwed in 'more or less to suit the distance between the wall H and the closet, and this nipple is usu ally long enough to allow for being sawed or filed oft if too long.

There is a clamp-ring, K, around this nipple D, so that a watertightjoint will be made by red lead or similar material between the end of the elbow F and the ringK and around the screw. l

At the upper end of the elbow F is a tubu lar socket adapted to receive within it the brass or other polished flushing-pipe M and the coupling ring N, screwed upon the outside of the elbow F at its upper end, and the inclosed washer O, of india-rubber or similar material, and with a brass ring, forms a tight joint against the smooth exterior surface of the pipe M after it has been raised or lowered to suit the position ofthe closet-cistern.

The upper end of the Vertical flushing-pipe M is screwed into the lower end of the compound curved coupling-pipe P, and at the upper end there is a tlange and couplingring, Q, by means of which the .flushing-pipe is connected at its upper end with the screw-socket R, that passes into the cistern S, as usual.

Ordinarily, the socket R is at some distance .from the wall; hence it is necessary to make the coupling-pipe P as a compound curve to pass at its lower end back to the wall, and this lower end may be moved laterally at the wall, so as to bring the flushing-pipe M correctly into position, so that the same may be accurately vertical.

I am aware that it is common to bend the lead iiushingpipe with a compound curve below the cistern; also, that devices for adjusting the lengths of tubular connections have been applied to basins, and screw-couplings havebeen applied to the porcelain tube upon water-closets. In my improvement I am able to connect up the brass flushing-pipe and to allow for all ordinary differences in placing the Closet and eistern without requiring any special changes or fittings, its heretofore indispensable.

I cla-inl as my invention- 1. The combination, with the vertical flushing-pipe M and the compound curved couplingpipe l), connecting the pipe M to the eistern, of the elbow F,hzwing :t socket at its upper end, into which the lower end of the pipe M enters, the coupling-ring N, and washer O, screw-nipple D, ring` K, und thimble B', and coupling c, snbstmitiully :1s set forth.

2. The combination, with the water-closet and eistern, of flushingpipe, M, of brass or similar material, adapted to be out off of the required length and having a smooth exterior surface1 the nipple D, connected with the Watercloset, the elbow F, screwed to the nipple 2o D and having a socket at its upper end for the reception of the lower end of the pipe M, and @screw-ring, N, and elastic packing for making a tight joint at the upper end of the elbow F, substantially as speeitied. 25

Signed by me this 3d day of March, A. D. 1887.

THEODORE BUTLER.
